What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Integrins consist of 24 species, each with unique tissue expression profiles and distinct biological functions. The β subunit of integrin interacts with the FERM-folded head domain of talin through an NPxY/F motif, triggering integrin activation. Although this motif is conserved across most integrin-β subunits, the precise molecular mechanism governing talin's selective recognition of different integrin-β subunits remains unclear. We identify two distinct configurations of the talin head when interacting with β2 and β3 integrins, providing critical insights into subunit-specific recognition of integrins. Structural studies reveal that mutations at the subdomain interface of the talin head can shift its β2-bound configuration to a β3-bound configuration. This shift enhances β2-integrin affinity, leading to increased lymphocyte function-associated antigen-1 (LFA-1)-mediated natural killer cell activity. Together, our data elucidate the structural basis of talin's role in mediating integrin activation in a subunit-specific manner and advance our understanding of how talin may regulate diverse functions of various integrin species.
